With the TrueSTEAM cover removed, you will see six DIP
switches to the left of the interface panel. This manual refers to
DIPs 1-6 from left to right. DIP 3, 4 and 5 offer different wiring
configurations for how to humidify. (DIPs 1-2 are associated with
maintenance. Details for DIPs 1-2 are found in the maintenance
section.) DIP 6 is not used at this time.

Before you Get started
TrueSTEAM wiring is different from evaporative pad humidifier wiring. TrueSTEAM is able to
monitor system power, and regulate system fan operation, in addition to solenoid water valve
actuation. These wiring features are configured by DIP settings.
DIP 3 = Wireless operation (applicable only on wireless models)
If DOWN (default) wireless terminal is disabled.
If UP, wireless terminal is enabled.
DIP 4 = Power monitoring.
If DOWN (default), TrueSTEAM looks for R input before
allowing humidity.
If UP, TrueSTEAM does not look for R input before allowing
humidity. Power is still allowed to pass through if R is wired.
DIP 5 = Back-up air proving.
If DOWN (default), TrueSTEAM does not look for air
movement (via air proving device) before allowing humidity.
If UP,
TrueSTEAM looks for air movement (via air proving
device) before allowing humidity. Wire an air proving device
between TrueSTEAM C and System C.
note:
Setting DIP 5 up requires DIP 4 to be down. If DIP 4 is up,
DIP 5 position will not be used.
